Description: SCP-5503 refers to 2 entities within the collective:

SCP-5503-1 is a plant/fungus type substance that is easily spread and capable of taking over a planet with a single spore if left unchecked. It spreads and grows at an alarming rate, and can grow on any organic surface. It will also be brought wherever SCP-5503-2 goes, coming out as -2 breathes. If no organic surface is within the area, SCP-5503-1's spores will continue to land on the surface, eventually forming a soil like substance that is not as fertile as any known substance, but does act as a suitable replacement. What it makes up in quick reproduction, however, it lacks in resistance, and is extremely vulnerable to most man-made creations, with fire being the most effective way of dealing with SCP-5503 as a whole
